All your issues seems to be gnuplot related. You should try experimenting
with gnuplot directly to see what works and what does not and report
the found problems to proper authorities, i.e. gnuplot people or even
better your binary distributor (Debian?).

Do you have font Vera.ttf installed?
Does GDFONTPATH point to the directory where it's
installed?


It is quite possible that your "MgOpenModernaBold.ttf" font is problematic,
though it should not make gnuplot to blow up (I do not have this font
and have no idea where do

The following works for me:

GDFONTPATH="/usr/share/fonts/bitstream-vera" gnuplot
gnuplot> set term png font "Vera.ttf"
Terminal type set to 'png'
Options are 'nocrop font Vera.ttf 12 size 640,480 '
gnuplot> set out "testpng11.png"
gnuplot> plot sin(x)

SVG font handling is somewhat more complicated (read help svg
on gnuplot prompt). The increased size of an SVG file may be due to
embedded fonts.

Sincerely,

Dmitri.
